Overview
The Decent DE1PRO is arguably the most technologically advanced espresso machine ever created for home use. Born from a Kickstarter project by software engineer John Buckman, the DE1PRO uses a thermoblock heating system paired with precision gear pumps to achieve something no other home machine can: real-time control of pressure, flow, and temperature simultaneously throughout the entire extraction. The machine connects to a tablet running the Decent app, which displays live graphs of pressure, flow, weight, and temperature — and allows the user to design custom extraction profiles or download community-shared profiles for specific coffees. The DE1PRO can replicate the pressure curves of virtually any espresso machine ever made, from a classic E61 to a La Marzocco Strada to a manual lever. Its thermoblock heats water on-demand with minimal waste, reaching brew temperature in about 20 seconds. At just 9.5 kg, it is remarkably light for its capability. The community around the Decent is exceptionally active, with thousands of shared profiles and ongoing firmware updates. This machine is for the data-driven barista who wants to understand and optimize every variable in their espresso.
The Decent DE1PRO comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction, pressure profiling for advanced shot manipulation, flow control for barista-level precision. It features a thermoblock boiler system made of stainless steel with a 10 ml capacity. The gear pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $3,499, the Decent DE1PRO is designed for passionate enthusiasts and semi-commercial users who accept nothing but the best. As a semi-automatic machine, it gives you control over the brewing process while handling pressure and temperature automatically.
In terms of build quality, the Decent DE1PRO is a substantial machine, weighing in at 9.5 kg, manufactured in Canada, drawing 1200W of power. With dimensions of 270 x 370 x 370 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 1000 ml, making it easy to set up anywhere in your kitchen.
Pros & Cons
Pros
- PID temperature control ensures consistent extraction temperature shot after shot

- Flow control gives barista-level precision over water flow rate during extraction
- Stainless steel boiler is corrosion-resistant and easy to maintain
- Standard 58mm portafilter is compatible with a wide range of third-party baskets and accessories
Cons
- Thermoblock heating may not match the temperature stability of traditional boiler designs
- Premium price point at $3,499 represents a significant investment

Who is the Decent DE1PRO designed for?
The Decent DE1PRO at $3,499 is a prosumer-grade machine designed for experienced home baristas who want near-commercial quality. It's not ideal as a first machine, but it's an excellent upgrade for those ready to invest in their espresso passion.
How often does the Decent DE1PRO need maintenance?
Regular maintenance includes daily backflushing (for machines with solenoid valves), weekly cleaning of the group head and portafilter, and descaling every 1-3 months depending on water hardness. Using filtered water significantly reduces scale buildup and extends machine life.
What grinder should I use with the Decent DE1PRO?
A prosumer machine like this deserves a premium grinder. Consider the Niche Zero ($600), Eureka Mignon XL ($700), DF64 variants, or premium options like the Weber EG-1 or Lagom P64. The grinder should match or exceed the machine's capability for best results.
Is the Decent DE1PRO worth $3,499?
The Decent DE1PRO's value depends on your commitment to espresso. If you drink espresso daily, a quality machine pays for itself vs. cafe purchases within 6-12 months. The Decent DE1PRO offers PID temperature control, pressure profiling, flow control at its price point, making it a sound investment for regular espresso drinkers.
